This is only a guess because I don't have your data:
sigma is must be positive in the dnorm function. My guess is that optim may
attempt an iteration with a negative sigma.
You may want to see help(optim) for dealing with this constraint.
Specifically see the lower argument.

You can also plot the +'s yourself using for example matlines:
# Some data
x - 1:10
y - 1:10
# Height and width of the crosses
dx1 - 0.1 # width in negative x-direction
dx2 - 0.2 # width in positive x-direction
dy1 - 0.2 # height in negative y-direction
dy2 - 0.3 # height in positive
That won't do much good. Tolerances don't add (except in rare
circumstances), and certainly not when they're in different units.
There's nothing wrong with the first part, i.e. setting up variables
whose contents include the mean and the tolerance, but is that peak? or
sigma? and so on.
